Sibling for big sister Tove Seraphina?

When you hear ToveSeraphina, what would you expect her brother to be named?
Her name is pronounced TOH-V.
Looking for some new name suggestions since we can't come up with anything we can agree on.
If baby is a girl she will be Zara, Catalina (Lina) or Genevieve (Veve)
Thank you!
